The first part of this paper presents a theoretical model, named UX-FFE, which combines a user eXperience (UX) approach with an upstream innovation process. The main interest of this UX-FFE model is that it allows to evaluate the social aspect of the upstream innovation process, which may be detrimental to the success of radical innovation projects in mature companies. The second part presents the outcomes of the experiment of the model application for the ideation stage of the upstream innovation. The objective of this experiment is to evaluate how much the designed bipolar mixed-method instrument and construct are reliable enough. Finally, the results permit, from the original structure of the UX-FFE model, to construct an instrument UXi dedicated to evaluate the user eXperience of co-creators in ideation stage.
